  • the first partition face 17p is formed to define the first osculation edge face 17s
  • the second partition face 25p is formed to define the second osculation edge face 25s. Accordingly, when the first and second osculation edge faces 17s and 25s come into tight contact with each other, the inside is divided by the partition 25z into the two insulation spaces 40x, 40y. With changes in number or shape of the partition 25z, the number of the insulation spaces 40 may be changed.
  • concave parts are formed on the inner side of the first and second osculation edge faces 17s and 25s to form the insulation space 40 in this embodiment, a concave part may be formed on the inner side of only one of the first osculation edge face 17s and the second osculation edge face 25s to form the insulation space 40.
  • the insulation space for refrigeration 40x is interposed to link the inflow holes 17a and the outflow holes 17b, thereby forming cold air flow paths from the refrigeration chamber 10x to the duct RD.
  • the insulation space for freezing 40y is interposed to link the inflow holes 17a and the outflow holes 17b, thereby forming cold air flow paths from the freezer chamber 106 to the duct FD.
  • the evaporator for refrigeration 24x installed in the insulation space for refrigeration 40x is installed between the compressor 21, cooling fan 22, and condenser 23 and the second partition wall 17 to face the inflow hole 17a. Accordingly, the cold air brought into the insulation space for refrigeration 40x from the refrigeration chamber 10x through the inflow hole 17a efficiently passes the evaporator for refrigeration 24x.
  • the evaporator for freezing 24y installed in the insulation space for freezing 40y is arranged along the second partition wall 17 in series with the compressor 21, the cooling fan 22, and the condenser 23 and located farthest from the compressor 21. This may make the evaporator for freezing 24y difficult to be influenced by the heat from the compressor 21 and thus able to cool the cold air at lower temperatures.
  • the evaporator for freezing 24y is also arranged to face the inflow hole 17a, so that the cold air brought into the insulation space for freezing 40y from the freezer chamber 10y though the inflow hole 17a efficiently passes the evaporator for freezing 24y.
  • the cold air circulates through the ducts RD, FD, the cooling chamber 10, and the insulation space 40 (machine room) in sequence.
  • the cold air cooled by the evaporator for refrigeration 24x circulates in the refrigeration chamber 10x
  • the cold air cooled by the evaporator for freezing 24y circulates in the freezer chamber 10y. Accordingly, the cold air cooled by each evaporator 24 circulates in each separate cooling chamber 10.
  • the evaporator may be contained in an insulation space. This facilitates access to the evaporator and noticeably improves maintenance performance.
  • an evaporator corresponding to each cooling chamber may be controlled separately to circulate cold air in a proper temperature range and a proper humidity range for the cooling chamber.
  • a plurality of evaporators each producing different temperature cold air may be cooled by a set of a compressor and a condenser, making the device installation space (machine room) compact, and as a result, a receiving capacity of the refrigerator may increase without increasing the outward form of the refrigerator.
  • the insulation member interposed between the compressor or condenser and the evaporator makes it difficult to transmit the heat generated by the compressor or condenser to the evaporator, thereby improving the cooling efficiency.
  • each cooling chamber remains enclosed by the insulation material, preventing drastic increase in temperature of the cooling chamber.
  • Cold air cooled by an evaporator contained in each insulation space to have a different temperature range and a different humidity range may be guided to a cooling chamber with the same temperature range and the same humidity range, enabling more efficient cooling of the cooling chamber.
  • the evaporator for refrigeration which is used to cool the refrigeration chamber having a higher temperature range than in the freezer chamber, is placed at a place with a narrow installation space, a wider installation space for the evaporator for freezing used for the low-temperature freezer chamber may be secured, making it easy to employ a larger evaporator for freezing having better cooling capability.
  • contact areas between the evaporator for freezing and the compressor and condenser may be reduced and the distance between the evaporator for freezing and the compressor and condenser may increase. This makes it difficult to transmit heat generated by the compressor and condenser to the evaporator for freezing, which requires keeping as low a temperature as possible.
  • the cooling unit CU includes the pair of wind blowers RB, FB, as shown in FIG. 10.
  • the cooling unit CU in this embodiment has the insulation member 25 shaped like a box opened to the second partition wall 17, a pair of through holes 25e formed on a top wall 25d pushed up from the evaporators 24x, 24y, and the wind blowers RB, FB installed in between.

  • the evaporator 24 may be installed in the main refrigerator body BD.
  • the cooling unit CU does not include the evaporator 24.
